Three examples of marine genetically engineered organisms are:
1. AquAdvantage salmon is genetically engineered Atlantic salmon modified in order to achieve fast growth. A growth hormone-regulating gene of Pacific salmon is introduced in the genome of Atlantic salmon.
2. Grass carp was also modified by scientist in order to enhance its protection from contagious diseases. It has been modified with a transgene coding for lactoferrin (antibacterial function). So, the, survival rate of the modified Grass carp was doubled comparing to nonmodifeied fish.
3. Zebrafish is the most commonly used for modification because it has 1-cell embryo, with clear chorion so it is easy to be micro-injected with transgenic DNA.
Ecological systems often remain in balance if only one factor is altered.
I think when a drug is fat soluble, sniffing is a rapid and effective way to absorb it, the statement is true. Nonetheless, liquid solubility should not be too high, because highly fat-soluble drugs tend to have low solubility in water. For example Drugs administered nasally should be water-soluble as well as fat soluble. Fat soluble drugs are those drugs that dissolve in fats an example is antianxiety drug.
Answer: A protein acts as a pump and moves calcium ions from an area of low concentration to an area of high concentration.
There are primarily two types of the transport system which occurs through the cell membrane. These are Active transport and passive transport. Active transport facilitates the movement of substances from a medium of lower concentration to a medium of higher concentration. Energy is required for the movement of substances against the concentration gradient. This is accomplished by ATP ( adenosine triphosphate) powered pumps or some other source like an electrochemical gradient.
On the other hand, in passive transport, substances move from a medium of higher concentration to lower concentration.
As 
ions are moving from low to higher concentration via protein pump, therefore, it accurately describes the movement through active transport.
